Item 6. Indemnification of Directors and Officers.

General Corporation Law of the State of Delaware

Section 145 of the Delaware General Corporation Law (“DGCL”) provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses including attorneys’ fees, judgments, fines and amounts paid in settlement in connection with various actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation, such as a derivative action), if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, if they had no reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the case of any actions by or in the right of the corporation, except that indemnification only extends to expenses, including attorneys’ fees, incurred in connection with the defense or settlement of such actions, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation’s certificate of incorporation, bylaws, agreement, a vote of stockholders or disinterested directors or otherwise.

Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL or (4) for any transaction from which the director derived an improper personal benefit.

Certificate of Incorporation and Bylaws

Article Ten of the Registrant’s Restated Certificate of Incorporation states that:

No Director of the Corporation shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a Director; provided, however, that the foregoing provision will not eliminate or limit the liability of a Director (a) for any breach of that Director’s duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) pursuant to section 174 of the DGCL, as the same exists or as that provision hereafter may be amended or modified from time to time, or (d) for any transactions from which that Director derived an improper personal benefit. If the DGCL is amended or modified after the filing of this Restated Certificate of Incorporation to authorize corporate action further eliminating or limiting the personal liability of Directors, then the liability of a Director, in addition to the limitation on personal liability provided in this Restated Certificate of Incorporation, will be limited to the fullest extent permitted by that law, as so amended or modified. Any repeal or modification of this Article TEN by the stockholders of the Corporation will be prospective only and will not have any effect on the liability or alleged liability of a Director arising out of or related to any event, act or omission that occurred prior to such repeal or modification.

In addition, the Registrant’s Amended and Restated Bylaws (the “Bylaws”) provide that the Registrant will indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may be amended, any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person or a person for whom such person is the legal representative, is or was a director or officer of the Registrant or, while a director or officer of the Registrant, is or was serving at the Registrant’s request as a director, officer, manager, partner, member, member representative or other designated legal representative of another corporation or of a partnership, joint venture, limited liability company, trust or other enterprise, including service with respect to employee benefit plans, against all liability and losses suffered and expenses (including attorneys’ fees) incurred by such person in connection with such action, suit or proceeding. The Bylaws also provide that the Registrant will pay the expenses incurred by a director or officer in defending any such proceeding in advance of its final disposition, subject to such person providing the Registrant with specified undertakings. Notwithstanding the foregoing, the Bylaws provide that the Registrant shall be required to indemnify or make advances to a person in connection with a proceeding (or part thereof) initiated by such person only if the proceeding (or part thereof) was authorized by the Registrant’s board of directors. These rights are not exclusive of any other right that any person may have or may acquire under any statute, provision of the Registrant’s certificate of incorporation, bylaws, agreement, vote of stockholders or disinterested directors or otherwise. No amendment, modification or repeal of those provisions will in any way adversely affect any right or protection under those provisions of any person in respect of any act or omission occurring prior to the time of such amendment, modification or repeal.

The Bylaws also permit the Registrant to secure and maintain insurance on behalf of any of the Registrant’s directors, officers, employees or agents and each person who is, or was, serving at the Registrant’s request as a director, officer, employee or agent of another corporation, partnership, joint venture, limited liability company, trust or other enterprise for any liability asserted against and incurred by such person in any such capacity. The Registrant currently maintains directors’ and officers’ liability insurance providing coverage to the Registrant’s directors and officers.

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of a prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
